Welcome Message


Welcome to Singapore!

We are very glad to see so many of you at the 8th Symposium on Cavitation, CAV 2012. We are following the successful tradition of CAV symposia, this symposium is taking place now 26 years after its initiation event at Sendai in 1986.

Cavitation is such a rich basic fluid mechanic problem with multiphase flavor which does not get the odour of old science but continuously challenges us. In this symposium we will hear of unsolved problems dating back from the first symposium while very new and exciting ones surface. One of such problems is cavitation in manufacturing, for example to remove smallest dirt particles from most delicate nano-structured surfaces with bubbles driven at high frequency ultrasound. Another emerging field is the medical use where a controlled cloud of cavitation bubbles moulds tissue into a liquid paste.

Still, we will see that cavitation remains an engineering challenge, in particular as we strive to have very large hydro-power plants, want to greatly increase the size of container ships, or the efficiency of engines. Nowhere have we seen any final solutions, but only a possible roadmap that pushes the limits to avoid, to contain, or to make use of cavitation.

The CAV series offers us a place to meet and renew the friendship with so many of our “Dear bubble friends” every three years, whether in Europe, US, or Asia. In 2012 the Nanyang Technological University, the National University of Singapore, and the Institute of High Performance computing are hosting the CAV symposium.

Before we kick-off CAV2012 we want to mention that this symposium has been shouldered on many, and our thanks goes to the conference organizers, the international scientific committee, our sponsors and organizing institutions, the financial administration at NTU, and the great local organizing committee. This wonderful team helped to get the strings tight together; now we can focus and celebrate the coming days on cavitation.
